Tranny Flush time...

[wontonrunner]

So I am approaching 60,000 miles and the previous owner never did a flush as required at the 30,000 mile mark...I do know however that the truck was a daily driver and that it only occaisonally saw a load behind it.

So it is time for a flush. I have been shopping around...kinda sorta, with the limited options being the 2 ford dealerships in town...one wants $450 and the other one will do it for $350...****ting thing is that they were only charging $250 6 months ago. (all prices in Canadian Dollars)

Well, I happened to be talking to a guy at the old ladys BBQ and it turns out he owns a Transmission shop. I asked him if he had any alternatives to the price ford transmission fluid and he told me that Wynn's has a full synthetic transmission oil and that they offer 320,000km warranty on the transmission if you get a flush done with it every 50,000km's starting with the first flush at 50,000 kms. If you don't get the first one done at 50,000km's with the wynns product then they reduce the warranty down to someting like 200 or 250,000km's...which is still above the 160,000 that ford offers.

I was just wondering if anyone else had heard this of had flushes down with other manufacturers oil. From what i understand, ford is the only approved oil for this transmission...but there has to be something else out there.

Maybe a pro can add some light to this issue as well. but it is my understanding that you should never perform a "engine" or "tranny" flush. the reason being the flushing agent will contaminate the oil/fluid causing premature failure to the componet. The owner should only drain, change filters, and refill.... NOT FLUSH

I know this is fact on my fathers Titan... is this true for fords/all vehicals?

it makes sense to me though

Flushing the tranny is the ONLY way to replace ALL the fluid. When dropping the pan, you only replace about 45% of the fluiid, and there isn't a drain plug on the TC.

To the OP. I'm planning on doing the flush on mine, using BG full synthetic. It will cost me about $325 American. BG is compatable with Ford fluid, and some say the truck will shift better with BG than the Motorcraft

Geez,I paid $99 for a flush last year with factory fluid,why so high these days.

I just went through this on a couple different vehicles and talked to a lot of people, some mechanics, some just the armchair old timers. It seems most of the crap that is in your transmission accumulates on that big nasty magnet on the drain plug...which makes sense. As far as the fluid breaking down, everyone seems to agree it can go a very long way. After filtering through (pun) the advice I received, it seemed like the best way to go was to replace the fluid and trans filter and add a bypass filter which would filter the fluid down to a finer level. For extra safety you can add one of those filter mags through summit or whoever you know carries them. Personally, im considering just getting some cow magnets, ziptie them together and drop them in plasti dip and strapping them to the filter. The full flush seems kind of like a dealer ploy after all the info i got. They'll even change your blinker fluid and re torque your whirly gig for only 399 extra.

seems to me that this is a way to give the tech a oppurtunity to halfass the job. its like getting an oil change and not change the fiter too.

the PDF is a double... sorry...

that amsoil proceedure is simlilar to another one that i found before online. However, by the time i buy the oil from ford and then the external filter...there is not much difference from gettting ford to do it..but from what i understand, they use a flush machine and dont address the interior filter.
I heard there is a special tool for removing the external filter on my job 1...is this true or is this just rumour?

If you do a BG flush the have a "Lifetime Protection Plan" that will cover you.... The BG Synthetic ATF is amazing stuff..... for a local shop that uses these products go to BG Find a shop this is good in the U.S as well as Mexico and for more info go to BG Products... I have used this stuff for 15 years in the dealers I have worked at I have also used the Wynn's products as well as JB and nothing compares to BG....

There are a lot of gimmicks out there but one thing you need to know is that fluid oxidizes and breaks down, period. The abuse that these trucks get is up there, well at least mine anyway, and its cheap insurance...... If you've ever had a gold fish did you ever just drain out half of the sh_t filled water and top off with new? If you did what did you see? All that sh_t get kicked up and contaminate all of you old fluid and that is exactly what happens in your transmission..... You need to make sure you get one done with a machine that doesn't have a 12v motor or other power source and use one that does do a 1:1 exchange that uses the trans pump to cycle the fluid. This horse has been kicked in the teeth time and time again and I will always say spend the money and do the flush.
